Ooooh, I've been in lots of these (although not the one you asked about!).

38 Bath St is nice, lovely apartments and good service

Glasgow lofts aren't worth the cash and the surrounding apartments are filled with some very dubious characters, maids were useless, service from managers and security even worse (they wouldn't let my mum up for a coffee at the weekend as "she wasn't down as staying there")

Dreamhouse apartments on Lynedoch Cres are ace, my favourite, expensive but worth the cash, especially for a longer stay

The Spires are quite good, but very noisy for me, especially at weekend

I stayed in some on St Vincent st too, but not sure if they are still there, were OK but a bit tatty.
